Mason Gideon and the Glass Tower (Paperback) (ISBN-13: 9798992283648)

A New Threat Rises...

Mason Gideon is no stranger to surprise. After learning that he is the time-displaced son of King Arthur, he and his friends embarked on a perilous quest to retrieve the legendary sword Excalibur. Months later, he now trains to earn his knighthood with the very powerful - and very strict - Order of the Knights of the Round Table.

However, more surprises abound and even he isn't prepared when the terrifying witches of the Elfennau attack. They threaten to eliminate the Order entirely unless Mason surrenders Excalibur. To stop them Mason, along with his brave friends Rhys and Elizabeth, embark upon a new adventure to find Excalibur's mystical scabbard - a magical item with the power to defeat the Elfennau.

Their journey leads them to discover the secrets lying within the ruins of Stonehenge. Can they solve the mystery of the ancient Wonder and defeat the Elfennau? Or is there something even worse waiting for them if they do?
